How to preserve NL in Ksh variables?
I'm trying to set a variable to the output of a command.

This is what the comand output to the display looks like:
Code:
 
/>hciconndump -v TOsiu
Dump of connection(s): TOsiu
----------------------------------------------------------------------
  Process: A60Tsiu              Connection: TOsiu
  EO Proc:
EO Config:
   EO Msg:
   Groups:
Data Type: frl                               Options: AUTO
RecoverDb: Yes               Hold: No       SendOnly: Yes
Disk msgs: No
Save Msgs:  in: No   Inbound File: TRsogaITS
           out: Yes Outbound File: TOsiu
Comm Type: pdl-tcpip
     Mode: Client   Port: 18001              Host: 131.230.236.21
Reconnect: Yes    Reopen: 5
      PDL: mlp_tcp.pdl
----------------------------------------------------------------------

When I set my variable equal to the results of this command all the NL in the output are apparently lost. I want to preserve the output in my variable exactly as it is displayed on the screen so that I can ECHO it later and it looks correct.
Code:
/>myvar=`hciconndump -v TOsiu`
hsdvim1b@hci (/qdxtest/qdx5.4/integrator/msjsf2)
/>echo $myvar
Dump of connection(s): TOsiu ---------------------------------------------------------------------- Process: A60Tsiu Connection: TOsiu EO Proc: EO Config: EO Msg: Groups: Data Type: frl Options: AUTO RecoverDb: Yes Hold: No SendOnly: Yes Disk msgs: No Save Msgs: in: No Inbound File: TRsogaITS out: Yes Outbound File: TOsiu Comm Type: pdl-tcpip Mode: Client Port: 18001 Host: 131.230.236.21 Reconnect: Yes Reopen: 5 PDL: mlp_tcp.pdl ----------------------------------------------------------------------

Is there a way to tell Unix Ksh to preserve the NL when assigning command output to a variable?

Thanks!
Troy

pdl::pptemplate

pptemplate(3)						User Contributed Perl Documentation					     pptemplate(3)

NAME

       pptemplate - script to generate Makefile.PL and PP file skeleton

SYNOPSIS

	       # generate Makefile.PL and mymodule.pd in CWD
	       pptemplate PDL::MyModule;

DESCRIPTION

       The pptemplate script is the easiest way to start a new module for PDL that contains PP code (see also PDL::PP). The usage is simply

	 pptemplate modulename;

       As a result pptemplate will generate a perl Makefile for the new module (Makefile.PL) that contains the minimal structure to generate a
       module from PP code and also a skeleton file for your new module.

       The file will be called mymod.pd if you called "pptemplate" as

	 pptemplate PDL::CleverAlgs::Mymod;

       I suppose you can work out the naming rule ";)". If not resort to experimentation or the source code.

       "pptemplate" will refuse to overwrite existing files of the same name to avoid accidents. Move them out of the way if you really want to
       scrap them.

   Options
       Currently there is only the "-i" option which switches "pptemplate" into the so called internal mode.  It should only be used when you are
       starting a new module within the main PDL tree that is supposed to be part of the PDL distribution and the normal PDL build process, e.g.

	  cd PDL/IO;
	  mkdir Mpthree; cd Mpthree;
	  pptemplate -i PDL::IO::Mpthree;

BUGS

       Maybe ";)".  Feedback and bug reports are welcome.
